According to YouTube, the Australian cast of The Lion King were "so elated" by the Brisbane season launch announcement that they decided to delight the people on their flight back to Sydney with an impromptu version of "Circle of Life."

The woman singing lead is Buyi Zama, who plays Rafiki in the show. She's currently recording an album titled ZULUCHYLD, according to Twitter.

Some of the other passengers seem to just stare into middle-distance with that dispassionate eyes-glazed-over gaze so common in airports, train stations and bus stations, but there are a few passengers who really got into it. How would you react?
